SN75178BPSRG4

Overview

The SN75178BPSRG4 is a single-channel RS-422/RS-485 line driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and draws a supply current of 57mA. The device features a propagation delay of 19ns and functions reliably across an operating temperature range of 0°C to 70°C. Housed in an 8-SOIC package with a width of 5.30mm, it supports surface-mount installation. This component complies with RoHS3 standards and carries an EAR99 classification.

Feature Summary

Provides differential signaling for RS-422 and RS-485 communication protocols
Designed for high-speed data transmission with low propagation delay characteristics
Compatible with standard 5V logic levels for easy system integration

Applications

Industrial control systems requiring robust differential bus communication
Multi-drop networks utilizing RS-485 protocol standards
Data acquisition systems interfacing with remote sensors

Procurement Notes

Verify the G4 suffix indicates lead-free construction and compliance with RoHS3 directives as per manufacturer documentation. Confirm the SOIC-8 package dimensions match PCB footprint requirements. Check for obsolescence status or lifecycle notices from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a single-channel driver is required for half-duplex RS-485 applications. Ensure the 57mA supply current fits within the system power budget. Verify that the 0°C to 70°C industrial temperature range meets environmental constraints. Compare against quad-driver alternatives if multiple channels are needed.

Part Context

This part belongs to the SN7517x family of interface ICs from Texas Instruments. It serves as a complementary driver to receivers like the SN75176. The family is widely used in legacy and modern industrial interfaces. The G4 suffix denotes specific manufacturing process updates ensuring environmental compliance.

Replacement Considerations

Direct pin-compatible substitutes include the SN75178BP and SN75178DR. Verify electrical parameters such as propagation delay and supply current match original design requirements. Check package availability and lifecycle status for alternative manufacturers.
